Cardiovascular and hepatic toxicity of cocaine: potential beneficial effects of modulators of oxidative stress

Oxidative stress (OS) is thought to play an important role in the pharmacological and toxic effects of various drugs of abuse. Herein we review the literature on the mechanisms responsible for the cardiovascular and hepatic toxicity of cocaine with special focus on OS-related mechanisms. We also review the preclinical and clinical literature concerning the putative therapeutic effects of OS modulators (such as N-acetylcysteine, superoxide dismutase mimetics, nitroxides and nitrones, NADPH oxidase inhibitors, xanthine oxidase inhibitors, and mitochondriotropic antioxidants) for the treatment of cocaine toxicity. We conclude that available OS modulators do not appear to have clinical efficacy

Veg*ns’ and omnivores’ reciprocal attitudes and dehumanization: The role of social dominance orientation, ingroup identification, and anticipated reproach

Two studies compared omnivores’ and veg*ns’ attitudes and dehumanization tendencies toward each other and identified the social psychological factors explaining them. Study 1 (N = 208, Italians) showed that veg*ns’ hold less positive attitudes toward omnivores than the reverse, and attributed to them less human uniqueness and nature; these differences were explained by veg*ns’ stronger identification with the ingroup and higher perceptions of reproach from the outgroup, even if omnivores’ higher levels of social dominance orientation worsened their attitude toward veg*ns. Study 2 (preregistered, N = 200, mostly from UK) overall replicated Study 1 findings at the explicit level. Interestingly, omnivores’ and veg*ns’ implicit attitudes were equally positive (but less positive than self-reported attitudes) and not predicted by the same mediators associated with the explicit measures. This work suggests that neither veg*ns nor omnivores hold negative attitudes toward each other: they were both positive or neutral toward the outgroup, even if at the explicit level this positivity is greater for omnivores

So Far, So Close: Identification with Proximal and Distal Groups as a Resource in Dealing with the COVID-19 Pandemic

A robust body of research has highlighted the fundamental role of social identifications in dealing with emergencies and in predicting commitment behaviors. We report the results of two studies carried out in Italy to assess whether the subjective sense of belonging to meaningful proximal and distal social groups affected people’s ability to cope with the pandemic crisis. Study 1 (N = 846) shows that different identifications with proximal (i.e., family and friends) and distal social groups (i.e., nation, European, and humankind) may act as buffers for individuals by reducing negative emotions and negative expectations about the future after COVID-19 and by increasing people’s intentions to adhere to containment measures and to be involved in prosocial actions. Study 2 (N = 350) highlights the role of European identification in predicting propensities for using the tracing app and getting vaccinated. These results confirm the benefits of various types of identification (proximal vs. distant) in helping individuals deal with the COVID-19 pandemic

The Evolutionary Scenario of Pediatric Unclassified Primary Antibody Deficiency to Adulthood

background: unclassified primary antibody deficiency (unPAD) is a relatively novel inborn error of immunity (IEI) condition that can vary with time to more defined entities. since long-term follow-up (FU) studies are scarce, we aimed to provide insight into the evolutionary clinical and immunological scenario of unPAD children to adulthood and identification of biomarkers of primary immune deficiency (PID) persistence. methods: a total of 23 pediatric unPAD patients underwent clinical and immunological FU for a mean time of 14 years (range 3-32 years, median 16 years). results: UnPAD diagnosis may change over time. at the last FU, 10/23 (44%) children matched the diagnosis of transient hypogammaglobulinemia of infancy and 13/23 (56%) suffered from a persistent PID. In detail, an unPAD condition was confirmed in 7/23 (30%) patients, whereas 3/23 (13%), 2/23 (9%), and 1/23 (4%) were reclassified as common variable immunodeficiency, selective IgA deficiency, and isolated IgM deficiency, respectively. Low IgA, low specific antibody response to pneumococcus, and lower respiratory tract infections at diagnosis were independently associated with IEI persistence. conclusions: long-term monitoring of unPAD patients is required to define their outcome and possible evolution towards a definitive IEI diagnosis

The Inborn Errors of Immunity—Virtual Consultation System Platform in Service for the Italian Primary Immunodeficiency Network: Results from the Validation Phase

purposeInborn errors of immunity (IEI) represent a heterogeneous group of rare genetically determined diseases. In some cases, patients present with complex or atypical phenotypes, not fulfilling the accepted diagnostic criteria for IEI and, thus, at high risk of misdiagnosis or diagnostic delay. this study aimed to validate a platform that, through the opinion of immunologist experts, improves the diagnostic process and the level of care of patients with atypical/complex IEI.MethodsHere, we describe the functioning of the IEI-Virtual consultation system (VCS), an innovative platform created by the italian Immunodeficiency network (IPINet). resultsIn the validation phase, from January 2020 to June 2021, 68 cases were entered on the IEI-VCS platform. a final diagnosis was achieved in 35/68 cases (51%, 95% CI 38.7 to 64.2). In 22 out of 35 solved cases, the diagnosis was confirmed by genetic analysis. In 3/35 cases, a diagnosis of secondary immunodeficiency was made. In the remaining 10 cases, an unequivocal clinical and immunological diagnosis was obtained, even though not substantiated by genetic analysis. conclusionFrom our preliminary study, the VCS represents an innovative and useful system to improve the diagnostic process of patients with complex unsolved IEI disorders, with benefits both in terms of reduction of time of diagnosis and access to the required therapies. these results may help the functioning of other international platforms for the management of complex cases

Sudden Unexpected Deaths and Vaccinations during the First Two Years of Life in Italy: A Case Series Study

Background The signal of an association between vaccination in the second year of life with a hexavalent vaccine and sudden unexpected deaths (SUD) in the two days following vaccination was reported in Germany in 2003. A study to establish whether the immunisation with hexavalent vaccines increased the short term risk of SUD in infants was conducted in Italy. Methodology/Principal Findings The reference population comprises around 3 million infants vaccinated in Italy in the study period 1999–2004 (1.5 million received hexavalent vaccines). Events of SUD in infants aged 1–23 months were identified through the death certificates. Vaccination history was retrieved from immunisation registries. Association between immunisation and death was assessed adopting a case series design focusing on the risk periods 0–1, 0–7, and 0–14 days after immunisation. Among the 604 infants who died of SUD, 244 (40%) had received at least one vaccination. Four deaths occurred within two days from vaccination with the hexavalent vaccines (RR = 1.5; 95% CI 0.6 to 4.2). The RRs for the risk periods 0–7 and 0–14 were 2.0 (95% CI 1.2 to 3.5) and 1.5 (95% CI 0.9 to 2.4). The increased risk was limited to the first dose (RR = 2.2; 95% CI 1.1 to 4.4), whereas no increase was observed for the second and third doses combined. Conclusions The RRs of SUD for any vaccines and any risk periods, even when greater than 1, were almost an order of magnitude lower than the estimates in Germany. The limited increase in RRs found in Italy appears confined to the first dose and may be partly explained by a residual uncontrolled confounding effect of age

Data acquisition and monitoring for the KLOE detector

none77siThe Data Acquisition system for the KLOE experiment, presently running at the Laboratori Nazionali di Frascati DAPhiNE collider, has been designed to sustain an acquisition throughput of 50 Mbyte/s for an event rate of 10 kHz. its two major components are the front end data readout, based on custom buses, and a complex network of computers and storage devices hosting a set of distributed processes. The end result is a seamless data transport from the readout system to the storage library, accompanied by concurrent on line calibrations and data quality control.openA. ALOISIO; F. AMBROSINO; S.
